Conditions that tie a use to one class or occupier

A planning condition restricting use to a named class or occupier beats the Use Classes Order every time it is properly worded. Class E flexibility, the freedom to run a shop, a cafe, a gym, a nursery or an office from the same unit without applying for anything, only exists because section 55(2)(f) of the Town and Country Planning Act 1990 says a change within a class is not development. That subsection is expressly subject to any restriction in the planning permission. So one sentence on a decision notice from 2011 can lock a unit into retail for good.

Architects and agents meet this most often when a client buys a unit, checks the Use Classes Order, concludes no permission is needed and then finds a condition attached to a permission granted decades ago.

Why councils impose them

The honest reasons are usually about impacts that differ between uses in the same class. A retail unit and a nursery in the same building generate different trip patterns at different times of day. A cafe wants extraction that a bookshop does not. An office in a residential street is quiet at night; a gym is not.

Councils also use them to protect a policy objective: keeping active frontage in a designated shopping area, holding employment floorspace, or preventing a use that would undermine an allocation. Where the local plan has a policy of that kind, the condition is normally defensible.

The weaker reasons are habit and caution. Conditions copied from a standard library, attached without a site-specific justification, are the ones worth challenging.

The six tests

The Planning Practice Guidance sets out six tests every condition must meet. It must be necessary, relevant to planning, relevant to the development permitted, enforceable, precise and reasonable in all other respects. A use restricting condition tends to fail on the first and the fifth.

Necessity is the sharpest test. If the impact the council is worried about would be acceptable across the whole class, the condition is not necessary. If only one alternative use in the class would cause harm, a condition excluding that use is proportionate and one excluding all of them is not.

Precision matters because the condition has to be enforceable years later by someone who was not involved. A condition saying the premises shall be used for the approved purpose only is imprecise, because the approved purpose is a description of development rather than a defined use. A condition naming the class and expressly excluding other uses in the same class does the job.

Personal permissions and occupancy conditions

A personal condition ties the permission to a named individual or body. When they go, the permission goes. The guidance treats this as exceptional, and rightly so: it strips the permission of value on sale and makes the property hard to mortgage.

The situations where it holds up are narrow. A use that is only acceptable because of the applicant's particular circumstances, such as a temporary business run by an occupier of the site, is the usual example. Agricultural and rural workers' dwellings use a related device, an occupancy condition tied to a category of worker rather than a person, and those are easier to justify because they attach to a defined need rather than an individual.

If a council proposes a personal condition, ask what harm it prevents. If the answer is that a different operator might behave differently, the answer is an operational condition on hours, deliveries or plant noise, not a personal one.

Reading a decision notice properly

Old permissions hide restrictions in three places. The description of development is the first: a permission for "change of use to A1 retail shop" describes what was permitted, and while a description alone does not usually restrict future changes, it frames the reading of the conditions.

The conditions are the second, and the wording has to be read closely. Look for the phrase "and for no other purpose", the words "notwithstanding the provisions of the Town and Country Planning (Use Classes) Order", and any reference to the General Permitted Development Order.

The third place is the approved plans and any legal agreement. A section 106 obligation can restrict occupation independently of any condition, and it does not disappear when a section 73 permission is granted unless it is varied by deed.

Check the whole planning history, not the most recent permission. A restriction imposed in 1998 survives a later permission for a shopfront alteration.

Getting the condition removed

Section 73 of the 1990 Act allows an application for permission to develop without complying with a condition. The council can grant permission subject to different conditions, or refuse. The application fee is lower than a full application, and the eight week determination period applies to minor development.

Three points decide these applications in practice.

1. Show what has changed. The policy background, the character of the parade, the tenant mix, the local plan that has been adopted since. A section 73 that simply asserts the condition is unnecessary invites the same officer to reach the same view.
2. Offer a narrower condition rather than nothing. Councils accept the removal of a blanket restriction far more readily when it is replaced by a condition dealing with the actual concern, such as an extraction specification, a delivery window or a limit on hours.
3. Deal with the impact evidence directly. Where the concern is fumes and odour, an Ventilation and Extraction Statement covering duct routing, termination height and filtration answers it. Where it is trips and parking, a short Transport Statement comparing the trip generation of the restricted use with the proposed one does more than argument.

A section 73 permission is a fresh permission. It cannot be used to change the description of development, and the original permission survives, so the decision notices need to be kept together.

The Levelling-up and Regeneration Act 2023 inserted a further route, section 73B, allowing variation where the effect is not substantially different from the original permission. Check the commencement position before relying on it, because the sections of that Act have been brought into force in stages.

When to appeal instead

An appeal under section 78 against a condition can be the better route where the council will not engage. The risk is real and often understated: on appeal the inspector deals with the application as if it had been made to them at first instance, so the permission as a whole is back in play rather than the disputed condition alone. Where the underlying use is uncontroversial that risk is small. Where the permission was finely balanced, it is not.

Householder and minor commercial appeals go through written representations in most cases. The deadline is six months from the decision for a full application, and twelve weeks for a householder appeal, so diarise it on the day the notice arrives.

Set the argument out in a Planning Statement that quotes the condition, gives its reason as stated on the notice, tests it against each of the six tests in turn, and offers replacement wording. Officers respond to that structure because it maps onto the report they have to write. If you want to see which supporting documents a change of use application usually needs, the full list of report types is grouped by category.

This is general guidance rather than legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
